Specification of Letters Patent.

Patented June 22, 1915.

Application filed June 6, 1914:. Serial No. 843,591.

To all whom it may concern Be it known that I, Jn'rrino THOMAS .WAnn, ofthe city of Peterborough, in the county of Northampton, England, haveinvented certain new and useful Improve ments in Demountable Wheels, ofwhich the following is the specification.

The invention relates to an improvement -1Il vehicle wheels andrefers-more particularly to an improved form of hub for the wheels andthe object of the invention is to provide an improved a wheel can beremoved and replaced, the complete operation being eficcted in a shortinterval of time and without the employment of a considerable number oftools as is now customarily required.

With the above object in view the invention consists essentially of aninner carrier portion mounted on the axle and provided with outstandingparts, a second outer portion, fitted with cross openings, rigidlyattached to the wheel and fitting over the first named portion andprovided with projecting parts formed to pass into the cross openiacigsaforesaid and releasable means for locking the two portions togetherwhen brought together, the parts being arranged and constructed ashereinafter more particularlydescribed and later pointed out in theappended claims.

Referring now to the drawings in which like characters of referenceindicate corresponding parts in each figure; Figure l represents a sideView, parts in vertical section, of my improvement in wheels. Fig. 2represents a face view of the inner carrier and outer portions andassociated parts, certain portions being shown in section. Fig. 3represents a perspective view of the outer portion connected to thewheel. Fig. 4 represents a perspective View of the carrier portion.

1 represents the axle of a wheel on which I have mounted a carrierportion 2.

3 represents the second or outer portion .mounted on the carrier portionand releasably attached to the same in a manner later described.

The carrier portion comprises the followlug elcmentsy is a centralcylinder rotata ly mounted on the axle and supplied ;h an outstandingflange 5 having porthereof cut away to present openings id 8 ifor apurpose later a parent. 9 a iaac plate of the same radius as theconstruction whereby flange which plate is mounted on the cylinderimmediately adjoining the flange, being spaced therefrom by interveningribs 10 formed as part of the plate. Fastening screws 11 securethe'plate to the flange, these screws passing through the ribs as bestshown in Fig. 2 of the drawing. The facing plate has portions thereofcut away as indicated at 12, 13 and 14: thereby providing openings whichwhen the plate and flange are connected register with the cut awayportions of the flange and thereby provide continuous cross openings A,B and G in the periphery of the carrier portion. Ball bearings 15 areemployed to effect the mounting of the carrier portion on the axle.These can be of any approved construction and can be arranged in anydesirable manner. 16 is a locking ring mounted on the outer edges of theflange and facing plate and fitted in the present instance with threedistinct inwardly projecting webs 17, 18 and 19, the webs being normallyslidably received between the edges of the plate and flange and ridingso to speak on the ribs which it will be noticed terminate in eachinstance somewhat back from the peripheries of the plate and flange. Thelocking ring has the outer edges thereof fitted with spanner notches 20for the application of a I tool.

With the, above explanation it will be seen that the webs althoughnormally contained between the flange and plate can be projected intothe openings hereinbefore referred to by the turning of the'ring in aproper direction.

In order thatthe webs may be locked in their withdrawn or projectedpositions I have supplied a number of locking devices located betweenthe flange and the plate and between the ribs. Each locking devicecomprises a pivoted socket 21 carrying a permanent extending stem'22 atthe outer end of which I have mounted slidably a detent 23 having arounded end. A spring 24: is mounted on.the spindle between thedetentand the base of the socket. Each web is supplied with a notch 25which receives the detent at all times. The ribs are arranged to engagewith and limit the swinging movement of the detent. v

In referring to Fig. 2 of the drawing it will be seen that the webs arein the withdrawn position and locked in this position by the detents.Upon one turning the locklltll ing ring the detents are initially forcedin against the action of the springs until such time that the detentshave assumed a radial position after which instant the springs 0perateto aid in the turning of the ring and .finally effect the locking of theWebs in the extended position, this occurring when the detents haveswung over and engaged with the opposite ribs. The action is accordinglyentirely automatic, the locking devices effecting the locking of thering in its extreme turned positions.

The second portion 3 of the device is now described in detail: Itcomprises an outer cylindrical member 26 designed to receive the innercylindrical member at and carrying two opposing nave plates 27 and 28the carrier portion The'channels 33 are designed when the parts arebrought together to receive the webs in the projected positions thereof.

.l he construction herein described provides a very easy method olremoving the wheel from the vehicle for repair or other purposes as itis only a matter of turning the ring-to withdraw the webs from thechannels i The wheel can be pulled off by withdrawing it in a directiontoward the outer end or the Various other well known mechanicalarrangements might be readily suggested to effect in a releasable waythe fastening and locking of the two principal parts of the device but Iwish it to be distinctly understood that any such modified constructionsn'o'ectin )arts arran ed to )ass into the cross openings, the saidchannels being designed to receive; the webs upon the ring being turned,as and for the purpose specified.

2. The combination with a vehicle axle, of a central cylinder rotatablymounted on the axle and-having an out-standing flange with portionsthereof cut away at the periphery, a face plate secured to the flangeand fitted with openings registering with the flange openings, a lockingring rotatably mounted on the peripheries of the flange and facingplateand litted with inwardly -projecting webs slidably received betweenthe flange and plate, an outer cylindrical wheel carrying portionslidably mounted on the carrier portion and provided with spacedextending channeled members on the side next the flange, the saidmembers being designed to enter the openings in the flange and plate andhaving the channels arranged to receive the Webs when projectedby theturning of the ring and mains efl'ecting the locking of the ring in theprojected and withdrawn positions of the webs, as and for the purposespecified.
